1. Manual Wafer Butterfly Valve Description：
A butterfly valve consists of body ,stem ,disc , actuator (manual actuator, worm-gear actuator , aerodynamic actuator or electric actuator) , and wafer type butterfly valve can implement the process for turning on turning off and regulating the flow by the circumrotation of stem and disc that is droved by actuators.
A butterfly valve is a valve which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they are lower in cost to other valve designs as well as being lighter in weight, meaning less support is required.

5.FAQ
1. What is manual wafer butterfly valve?
A: Wafer style is the more common of the two and is less expensive than the lug style. The wafer style butterfly valve is just about the standard. It ís so common that no one even bothers to use the word "wafer" when ordering a butterfly valve. It is taken for granted that if a butterfly valve is ordered, a wafer style will be received.
2. How about the Installation of the Wafer Style Butterfly Valve?
A: Butterfly valves are installed by inserting the valve between two flanges using bolts or studs and nuts to hold it all together. This type of installation, of course, makes it impossible to disconnect just one side of the piping system from the valve. That benefit is received using the lug style valve.
3. What is the working principle of manual wafer butterfly valve?
A: A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to throttle flow.
- Q:I heard there are really fine valves, does someone possesses thoughts where to buy these goods? I heard about them on TV. Anybody alive?
- Any plumbing supply shop should have them as well as most home stores, but they are generally for a specific purpose such as at the bottom of a well pick up pipe. Basically a check valve to prevent water from draining back to the well when the pump is off, thus eliminating the need to prime the pump for every on cycle. Al
- Q:in engines otto cycle
- short answer more horse power.
- Q:i have a 1990 gmc sierra k1500, 4.3 v6. it has leaking valve seals its only smokes wen i first start it. so im not in to much of a hurry to replace them. wen i do replace them will i have to reset the timing and the valve gap? and could leaking valve seals cause loss of power or performance problems
- sounds like valve seals ! no you don,t have to bother the timing ! all you do is remove the plugs, hook up a air compressor and screw 1 end of the hose into the plug hole, take off the valve pan, loosen the rocker and start the compressor up ! once the compressor reaches about 40 to 50 pounds then take out the keeper on the valve stem and replace it with a new seal, if you can get the umbrella type seals, after the seal is replaced put the rocker back on, turn the crank by hand until the rocker is on the low cam and torque the rocker nut ! then you do the same way to the rest of the valve seals !
- Q:Friends,is there anyone know about LinX(Linear Exchage)Valve,how they work.thanks in advance
- A major improvement in the DWEER system has been the development of the LinX (LinearExchanger) valve, which was patented byShumway . This valve replaced eight two-way valves with asingle multi-port spool valve which simplifiedthe system, improved reliability, reducedmaintenance requirements and allowed for fastervalve switching, reducing the size (and thus cost)of the energy recovery vessels. DWEER systemsutilize long vessels which may be installed underthe membrane vessels. Atpresent, the largest available DWEER system has a capacity of 500 m?/h.

- Q:How do you remove a richdel sprinkler valve, when I turn the body of it, it doesn't unscrew, it just turns in place.
- is it the valve your trying to remove, or the sprinkler head? if its the valve, there will be two pipes, one in and one out, just unwind the thread at end end of the valve, If its the sprinkler itself, then there should be a pipe under the sprinkler(swing joint) just grab the whole body and unscrew ( make sure you grab the whole sprinkler and not just the top, you may have to dig around it
- Q:I know absolutely nothing about cars. My AC stopped working, I had a new air compressor, drier, expansion valve put on. It was also vacuumed out. Problem is it will not take a recharge, and there is no refrigerant in it at all. But it keeps reading high pressure, I don't know the readings I was told it is reading high, and will not take a recharge. Someone on yahoo answers suggested it might be the Schrader valve is this a problem that it can cause if it's bad that it will not let you recharge, and read a high pressure reading? Is there a Schrader valve for the low pressure valve amp; the high pressure valve or is there just one? I have a 96 Dodge Stratus ES. Thank you for any help or ideas.
- After replacing all these parts it should have corrected any restriction. If it was vacuumed out there should be negative pressure in the system and accept a charge through the low side port. If you did not see the actual work done im wondering if the parts were indeed changed?
- Q:I have a Chevy Silverado 2500 5.7L V8. I have been having problems with passing smog. First one failed because it needed a new cat. Replaced it and tested again. NOx emissions are off the chart (1450/1006 max of 992/59615/25mph). I replaced the EGR valve based on a suggestion. Quick test today said the NOx emissions are still way off. Suggested that I change the EGR solenoid valve and also pull the EGR valve and use a coat hanger to clean some of the carbon build up. I purchased a new solenoid today but looking at it I noticed something. Since there are what are appear to be two ports on one side of the solenoid, I must have replaced the vacuum hose onto the wrong one after replacing the EGR valve. How much would this make a difference on the test readings taken? Would it be beneficial to just replace the solenoid anyway or try to test again with the current one but connected properly?
- if the spark plugs are bad the oxygen sensor with sense the exhaust is not hot enough and the computer with allow the injectors to let more gas in thinking that since theres no fire it needs more gas causing it to run like its flooding and exhaust readings will be high. make sure the air filters clean
- Q:I threw a birthday party last night, all went well until 2am when a crazy (drunk!) lady cut all the wires from my heating system (i guess as a prank??? dunno, she is never invited back). I have everything up and running when using one thermostat and connecting the thermostat wires (red directly to tv, Brown directly to W, and white directly to T) and not using the two Honeywell zone valves (model number V8043F. How do I connect those two zone valves to the L8148E aquastat?The valves have on bottom Th-TR, TH and TR and the two top screws are labeled end switch.If you need photos I can take them :)Thanks in advance!

- Q:Whilst pumping up my new tubular tyre, the head of the presta valve snapped off! Because this is a tubular tyre, I spent a lot of time (and cash) gluing it on and applying it etc, so I'm reluctant to buy a new tub. Is there any way getting a new presta valve head without replacing the whole tyre?Thanks in advance.
- You will need a tube with a Presta valve installed. You cannot simply change the valve stems on your existing tubes. I have been riding Presta tubes in Schraeder rims on my mountain bike for years. I cut a piece of old inner tube about an inch in diameter and poked a hole for the Presta stem to go through. This has been enough of a gasket to keep the tube from being damaged. There are grommets that you can buy at bike shops to take up the slack, but I have never found them really necessary.
- Q:What would be some drivability issues with an EGR valve that is acting up. The valve in question is an electronic egr valve.
- EGR - Exhaust Gas Recirculation The EGR opens controls a valve that connects your exhaust manifold to your intake manifold. The EGR valve reintroduces engine exhaust back into the cylinders to reduce combustion efficiency during high rpms. This is to protect the engine and keep it from overheating. If you EGR is acting up and opening on low rpms then the car will spew out smoke due to unburned fuel and suffer from loss of power.
